UNITED STATES AUGUST BEHRSIN, OF LOS ANGELES, CALIFORNIA.

OIL BURNER.

Application filed November 5, 1923. Serial No. 672,850.

To all whom it may concern:

Be it known that 1, AUGUST Bnnnsin, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Oil Burners, of which the following is a specification.

This invention relates to a liquid fuel burner, and more particularly pertains to a burner adapted for the combustion of oil with steam.

An object of my present invention is to provide an improved two-fluid burner, especially adapted for the burning of oil, and the utilization of steam in so doing.

Another object of my invent-ion is to provide an oil burner which has an improved efficiency in the consun' ption of oil.

Another object of my invention is the provision of an oil burner which may be controlled with facility.

A still further object of my invention is to provide an oil burner which is capable of withstanding a heavy overload.

A still further object of my invention is the provision of an oil burner which will not be clogged by unburnt carbon.

Other objects may be inferred from a reading of the following specification:

In the drawings Fig. 1 is a plan view of. my oil burner as applied to afurnace.

Fig. 9 is an elevational view of an upper portion of the burner.

Fig. 10 is a cross section taken on line 101O of Figure 9.

More particularly, reference being had to Figure 3, 12 indicates the body portion of the burner which is here shown as comprising a cylinder 13 having an annular recess or groove 14 at its upper end, with a threaded inlet passage 15 extending from and which are ninety degrees apart, thesev passages emergmg between the annular mm 21 of the recess and a mound 22 projecting from the bottom of the recess and terminat ing flush withthe rim'21. A lug 23 attached to, or made integral with a part of the cylindrical surface of the cylinder 13, has a vertical channel 24 which is threaded at its lower end portion and extends nearly to the top of the lug. The lug 15 also has a horizontal channel or passageway 25 which is threaded at its outer end and communicates with the vertical channel 24. The horizontal channel 25 of the lug 15 is projected into the interior of the cylinder 13 out of communication with the channel 16 with a vertical passage or channel 26, threaded at its upper end, located centrally of the cylinder 13 and extending downwardly from the upper surface of the mound 22 into the interior of the cylinder until it communicates with the horizontal passageway 25.

In Figure 4 is shown a circular drip plate of larger diameter than the cylinder 13 which is adapted to seat on the rim 21 and is formed with a central circular aperture 32 of substantially the same diameter as the vertical channel 26 of the cylinder 13 and is adapted to register therewith. The drip plate 30 has two oppositely disposed perforations 33 and 34 for the purpose of engaging fastenings as later described. Outwardly of the central aperture 32 are positioned four equal arcuate apertures 36, 37, 38 and 39 so disposed as to be'located above the open upper ends of the passages 17, 18, 19 and 20, when the drip plate is assembled on the rim 21.

Figure 5 shows a steam distributing plate 40 having the general form of a star wheel gear, the diameter of which is substantially equal to the diameter of the cylinder 13. The steam distributing plate 40 has a central circular aperture 41 of substantially the same diameter as the central circular aperture 32 of the drip plate 30, and has eight radial slots 42 having curved diverging sides 43, the sides of one slot meeting the sides of its adjacent slot to form the tapered spurs 45 between adjacent slots. The extreme distance between the ends of the bottom wall of adjacent slots 42, as shown by line 46 in Figure 5, is substantially equal to the length of the median are 47 shown in Figure 4 of the slots 36, 37 38 and 39 of the drip plate 30. The steam distributing plate 40 has two oppositely disposed perforations 48 and 49, one in each of two spurs 45. The distance between the perforations 48 and 49 is equal to the distance between the perforations 33 and 34 of'the drip plate 30, and are for the purpose of engaging fastening means, as later described.

In Figure 6 is shown a circular partition plate or diaphragm 50 of substantially the same diameter as the steam distributing plate 40. The diaphragm 50 has a central circular aperture 52 and has perforations 53 and 54, the same distance apart as the perforations 48 and 49 in the steam distributing plate 40, the perforations being for the purpose of engaging fastening means, as later described.

In Figure 7 is shown'an oil distributing plate 56 which has a diameter equal to the diameter of the diaphragm 50. The oildistributing plate 56 has a central circular aperture 57 of the same diameter as the central circular aperture 52 of the dia phragm, and has eight radial slots 58 extending from its periphery towards the center and having converging sides 59. Between the slots 58 of the oil-distributing plate are segments 60*. The oil-distributing plate 56 also has two oppositely disposed perforations 61 and 62, the same distance apart as perforations 53 and 54 of the diaphragm 50, and are used for the purpose of engaging fastening means.

Figure 8 shows a cylindrical cap 64 having an aperture 65 passing axially therethrough which aperture leads to an annular recess 66 on the under side of the cap as shown in Figure 2. Outwardly of and con centrically with the recess 66 is a circular groove 67, the inner periphery of which is provided with radial apertures 68 which extend upwardly and interiorly to communiits axis.

c-ate with the recess 66.

In Figure 8 is also shown a bolt 72 having a head 73 and a threaded cylindrical stem 74. The stem 74 has a diameter equal to the central circular apertures in the plates 30, 40, 50, and 56, and equal to the diameter of thevertical aperture 65 in the cap 64. The stem 74 of the bolt 72 is hollow and has two opposite apertures 76 and 7 7 transverse of The stem 74 also has two other transverse opposite apertures 78 which are above the apertures 76 and 77.

In assembling the parts of the burner, the steam-distributing plate 40 is superimposed on the drip plate 30 so that spurs 45 of the steam-distributing plate bisect the apertures 363738 and 39 of the drip plate and so that the central circular aperture 41 of the steam distributing plate 40 is in alignment with the central circular aperture 32 of the drip plate. The perforations 48 and 49 of the steam-distributing plate 40 are also aligned with the perforations 33 and 34, respectively, of the drip. plate 30. The diaphragm 50 is then superimposed on the steam-distributing plate 40 in such position that the perforations and 54 of the diaphragm 50 are in alignment with the perforations 46 and 49, respectively, of the steam-distribuing plate 40 and in such position that the central circular apertures 52 of the diaphragm will be in alignment with the central circular aperture 41 of the steamdistributing plate 40.

The oildistributing plate 56 is then superimposed on the diaphragm 50 and aligned therewith. V hen the plates are in alignment it will be found that the oil-distributing plate 56 has its slots 58 overlying the slots of the steaiii-distributing plate 40, the diaphragm 5O lying between the slots of the oil-distributing plate and of the steam-distrilniting plate. The plates 30, 40, 56 and the diaphragm 56 may then be secured to each other by screws which are passed through the apertures in each plate provided for the purpose. The combined plates and diaphragm thus form a unit which is superimposed on the cylindrical body 13 of the burner, the drip plate 30 being in contact with the upper rim 21 of the cylindrical body 13.

The cap 64 is then superin'iposod on the oil-distributing plate 56 and aligned therewith. The bolt 72 may then be passed through the vertical aperture 65 in the cap 64, through the central vertical apertures in the plates 56, 40, and 30 and the diaphragm 50 and screwed into the upper portion of the vertical channel 26 in the cylindrical body 13 until the head of the bolt is in contact with the upper surface of the cap.

In the functioning of the device, the st 21111 is introduced into the channel 15 at the bottom of the cylindrical body 13. The steam then passes into the chamber 16 where it divides and passes through the four vertical passages l7, l8, l9 and 20. l lnicrging from these four passages the steam passes through the four slots 36, 37, 38 and 39 of the drip plate 30. The steam passing through any one of the slots 36, 37, 38 and 39 also passes vertically through two slots 42 in the steamdistributing plate 40 until itstrikes the diaphragm 50, when it is deflected from the vertical into the horizontal position and issues from the slots between the drip plate 30 and the diaphragm 50. The oil is introduced through either one or both of the apertures 24 and 25 in the lug 23. In case the oil is introduced through only the vertical aperture 24 of the lug 23, the other aperture 25 may be stopped with a plug 8O,

r and filtered with regulating valves shown in Figure The oil passes through the horizontal channel 25 in the cylindrical body 13 at the end of which it enters the vertical central channel 26 In its passage upwardly through the vertical central channel 26 the oil enters the interior of the stem 74 of the bolt 72- and continues its passage through the stem 7 until it emerges through the transverse openings 76, 77, and T8 in the stem. After emerging from the transverse openings the oil passes into and through the radial apertures 68 in the cap 64:. After emerging from the radial apertures 68 the oil passes through the slots 58 in the oil distributing plate 56 and is deflected in a horizontal direction by the diaphragm 50. On issuing from the slots 58 of the oil distributing plate 56 in a horizontal direction, the oil comes in contact with the steam issuing from the slots 42 of the steam distributing plate 40, whereupon the two fluids are properly combined for combustion.

It will be seen that the burner thus constructed is adapted to discharge the steam and oil radially thereof throughout the periphery of the cylindrical burner body which renders the burner admirably suitable for use in a cylindrical fire box 81, as shown in Figure 1; the burner being located centrally of the'fire box and connected to oil and steam feed pipes 82 and 83, respectively, leading from any suitable source of supply 84 and 85.

If, however, it should be desired to direct the oil and steam from one side portion of the burner only, an annular sleeve 86 may be disposed to encircle the cap 6 f as shown in Figures 9 and 10, which sleeve has a wall portion which extends over the discharge openings on the opposite sides of the diaphragm 50 and has a slot 87 through which a part of the discharge openings are exposed; the ends of the slot 87 having outwardly flared flanges 88 which serve as fuel spreaders in directing the fuel from the burner. The sleeve may be turned on the head (34 to direct the fuel from any desired side port-ion thereof.

While I have described in detail a preferred form of my oil burner, modifications thereof may easily be made without departing from the essence of the invention; for example, the steam and oil distributing plates may, if desired, have each only one slot instead of a plurality, as shown. However, I desire it to be understood that such modifications come within the scope of my invention.
